To ALL WHOM IT MAY oononnn:

Be it known that I, PETER WINTER, of Horicon, in t invented certain newand useful improvements in Process 0 he county of Dodge, and State ofWisconsin, have f Manufacturing 2. Brown 'Mctallic Paint: and I do Toenable others skilled in the art to construct and use my invention Iwill proceed to-describc it. My invention consists in a new and usefulprocess for making a line brown metallic paint from peroxide of iron andmanganese, known as dead or shot-iron ore. While the base of all othermineral paintsis clay and silica, my metallic brown is composed of thefollowing ingredients: Peroxide of iron, 84.46; sesquoxide of manganese,4.55; silica, 8.34; alumina, 2.65. I have discovered that the peroxde'ofiron andmanganese exists in some places in a naturalstate, and isproperly termed dead orfshot-iron' ore. In making my paint, I take thissubstance and subject it to the action of heat for several hours, .oruntil it softens snfliciently to be ground or pulverized into animpalpable powder; I then place it on iron plates, either in a furnaceor oven, and subject it to nearly a red heat for several'hours, By thisproeess,-the peroxide of iron is converted or changed to the red oiiide.Having thus treated the ore, I grind it, and afterward subject it tofurther heat, which greatly improves it. It may, however, be used forall common purposes without grinding. It will mix readily with linseedoil, and I use it for all common purposes without grinding. As a paintit flows easily from the brush and leaves upon the surface a glossy,unfailing, durable,"brown metallic coat, which hardens by exposure, andis unafiected by the weather of any climate or by sea-water. Incombination with other paints it gives any covered by it becomeswater-proof, is preserved from rot, an

What I claim, is I I The brown metallic paint manufactured from thesuhstanee popul sisting mainly of peroxide of iron and manganese, whentreated substa (1 does not crack when rolled,
